Abstract

Hydrogen production by water splitting with MnFe2 O4 / Na2 CO3 system was studied at 973 K. An intermediate phase, resulting from decarbonatation of MnFe2 O4 / Na2 CO3 mixture in inert atmosphere, proved to be effective in hydrogen reduction from water with stoichiometric yield. The presence of a highly reactive intermediate phase suggests the feasibility of a high efficiency, three-step, thermochemical cycle for hydrogen production. In fact, the possibility of obtaining CO2 separately from the gases mixture dramatically enhances process efficiency. © 2006 International Association for Hydrogen Energy.
